SELF-INKIN'G HANDSTAMP.

To all whom t may concern:

Be it known that I, HARRY S. FoLGER, a citizen of the United States ofAmerica7 and a resident of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements inSelf-hiking Hand-Stamps, of which the following is a specification.

My invention relates to self-inking hand stamps and has for its objectimprovements in such stamps.

ln the accompanying drawings- Figure 1 is a front elevation;

Fig. 2 is a side elevation;

Fig. 3 is a section on line 3-3 of Fig. 2; Fig. 4L is a section on line44-4 of Fig. 3; and

F ig. 5 is a plan of the blank used in forming an interior frame orcasing which will here be called `a box.

The frame of the stamp, which has been called an outer frame in selfinking stamps of a similar character, consists of side plates 10 and 11connected together below by tie bolts '12. These side plates are formedof sheet metal and have long vertical slots 13 which extend from theupper ends of the plates to near the bottom. So made the plates 10 and11 are nearly cut in two by the open upper ends of the slots. The slotsare made long so as to give long guides for the movement hereinafter tobe described, and they are left open at the top because, to extend themetal of the side plates upward to close the upper ends of the slots,would i make the side plates strike the operators hand when operatingthe stamp unless the handle were made inconveniently long.

The weakness of the plates 10 and 11 caused by cutting slots 13 ispartly overcome by turning outward the flanges 14:, which flanges areformed from part of the metal removed to form the slot. These flangesserve to prevent lateral bending of the'upper parts of the side plates.The parts of the side plates below the slots 13 are also' stiffened bybeads 15 pressed into the metal as shown, one end of one o-f these beadsbeing made to serve an additional purpose to `be described.

A box 16 is formed from a piece of metal shown in Fig. 5, and bent alongthe dotted lines. The rectangular parts of this piece form the top,front and back of the box, while Specification of Letters Patent.Patented Aug, Application led. March 11, 1915. Serial No. 13,572.

the ends are formed by the wings 17. After being bent to position lthejoints are secured by soldering or brazing. A short straight piece ofmetallS has its ends bent into hooks 19 (Fig. 3), and this piece is theninserted into the lower open end of the box 16 and soldered in place. Asso constructed the edges of the box and the piece 18 form a channel forholding the removable type 20.

Extending through and supported in the `box 16 are shafts 21, whichshafts extend through the slots 13 and carry guide blocks 22 on theirends. These guide blocks or slides are in the form of channels whichernbrace and are guided by the flanges 14 on the side plates. As soarranged the shafts 21 act as tie rods between the upper parts of theside plates 10 and 11, and the channel form of the guide blocks 22causes these blocks to act as ties across the upper ends of the slots13.

On a shaft or rod 23 is pivoted a swinging frame 24 which carries aremovable ink pad 25 adapted to engage the face of the type 20. Links 26between the lower shaft 21 and the frame 24 serve to connect the box 1Gand pad frame 24 so that they move together. A spring 27 `(Fig. 1) onthe shaft 23 serves to elevate the box 16 and draw or force the j pad 25against the type 20. Pressure applied by hand to the handle 28 moves thepad rearward and the stamp downward to printing position.

Pivoted at 29 (Fig. 2) is a catch 30 adapted `to engage notches 31 inthe adjacent guide block or slide 22 to hold the stamp in a depressedposition against the action of spring 27. The catch 30 has a projection32 adapted to engage the end of the adjacent bead 15 to limit theoutward movement of said catch. This outer position is shown in Fig. 2and is such that the upper end of the catch projects slightly beyond theedge of the plate 10 to which it is pivoted. The inner position of thecatch is one in which the upper outer edge of said catch substantiallymatches the edge of the plate 10. As so constructed the catch 30 is madeto engage one of the notches 31, when the stamp is depressed, by simplypushing the thumb or finger along the edge of the plate 10.

At one end of the plate out of which the box 16 is formed are certainlugs 33 which are conveniently formed by punching them from the inetalof the plate. These are arranged so as to form a holder for the card 34located on the front face of the box 16.

The box 16 is shown tapered. It may, however, be of any form. Itsfunction is to provide a type holding channel below and serve as ahandle support above. Also, to furnish connections between the stanipand the guide blocks. By making the connection between the type channeland the handle of the box forni, the self inker is given a neatappearance. By making the box, the type channel and the card holder froma single piece of sheet metal there are economy and convenience inconstruction. The box form gives lightness and provides height whichprevents the hand from striking the frame when the stamp is depressed.The lowest position of the top of the box is preferably on a level withthe tops of the side plates 10 and 11.

What I claim is 1. In a hand stainp, a box formed of sheet metal, saidbox being closed above and on its four sides by the inetal from whichthe box is formed and providing a narrow opening below, and a bridgeinserted in the opening and secured to the box, the front and rear sidesof the box at the opening serving as the sides of a type holdingchannel, and the bridge serving as the bottoni of such channel. Y

. 2. In a self inking hand stamp, a box providing a type holding channelbelow and a handle connection above, said box being forined from aysingle piece of sheet metal bent to inclose all faces of said box exceptthat providing the type holding` channel, and a bottoni to said channel,said bottoni being formed by a strip of metal inserted in the open faceof said box and secured to the edges thereof.

3. In a hand stamp, a box forined of sheet metal bent to close the topand front and rear faces of the stamp and arranged to provide a narrowopening below, and a bridge inserted in said opening and secured to thebox, the front and rear faces of the box at the opening serving as thesides of a type holding channel, and the bridge serving as the bottoniand ends of such channel.

4. In a self inking hand stamp, a frame having two sections consistingof sheet metal plates having open ended slots in the upper end of saidplates, said slots being bounded on their sides by reinforcing fiangcsbent from the plates and having reinforcing beads extending below andaround the lower ends of the slots to stiften the plates at theseplaces, a reciprocating stamp in the frame, slides secured to the stampand operating upon the lianges as guides to guide the stamp in thefra-ine, and a catch pivoted to one plate and adapted to engage a notchin the adjacent slide to hold the stamp at a fixed position in theframe, said catch being arranged to engage the adjacent bead to limitthe outward movement of the catch, substantially as described.

5. In a self inking` hand stamp, a frame consistinoof side platesconnected together by tie rods, said plates having vertical slotstherein open at their upper ends and said plates being reinforced at theedges of the slots by anges bent froln the plates to form the slots, astamp located between the side plates and slides secured to said stampand arranged to embrace said {ianges so as to forin ties for the openupper ends of said slots.
